How to Create a Zone Cluster

Perform this procedure to create a cluster of non-global zones.

Before You Begin

• Create a global cluster. See Chapter 3, Establishing the Global Cluster.

• Read the guidelines and requirements for creating a zone cluster. See Zone Clusters.

• Have available the following information:

  • The unique name to assign to the zone cluster.

  • The zone path that the nodes of the zone cluster will use. For more information, see the description of the zonepath property in Resource and Property Types in System Administration Guide: Solaris Containers-Resource Management and Solaris Zones.

  • The name of each node in the global cluster on which to create a zone-cluster node.

  • The zone public hostname, or host alias, that you assign to each zone-cluster node.

  • The public-network IP address that each zone-cluster node uses.

  • The name of the public-network adapter that each zone-cluster node uses to connect to the public network.

1. Become superuser on an active member node of a global cluster.

   You perform all steps of this procedure from a node of the global cluster.

2. Ensure that the node of the global cluster is in cluster mode.

   If any node is in noncluster mode, changes that you make are propagated when the node returns to cluster mode. Therefore, you can create a zone cluster even if some global-cluster nodes are in noncluster mode. When those nodes return to cluster mode, the system performs zone-cluster creation tasks on those nodes.

3. Create the zone cluster.

   ---

   Note –

   By default, sparse root zones are created. To create whole root zones, add the -b option to the create command.

   ---

   phys-schost-1# clzonecluster configure zoneclustername clzc:zoneclustername> create Set the zone path for the entire zone cluster clzc:zoneclustername> set zonepath=/zones/zoneclustername Add the first node and specify node-specific settings clzc:zoneclustername> add node clzc:zoneclustername:node> set physical-host=baseclusternode1 clzc:zoneclustername:node> set hostname=hostname1 clzc:zoneclustername:node> add net clzc:zoneclustername:node:net> set address=public_netaddr clzc:zoneclustername:node:net> set physical=adapter clzc:zoneclustername:node:net> end clzc:zoneclustername:node> end Set the root password globally for all nodes in the zone cluster clzc:zoneclustername> add sysid clzc:zoneclustername:sysid> set root_password=encrypted_password clzc:zoneclustername:sysid> end Save the configuration and exit the utility clzc:zoneclustername> commit clzc:zoneclustername> exit

4. (Optional) Add one or more additional nodes to the zone cluster,

   phys-schost-1# clzonecluster configure zoneclustername clzc:zoneclustername> add node clzc:zoneclustername:node> set physical-host=baseclusternode2 clzc:zoneclustername:node> set hostname=hostname2 clzc:zoneclustername:node> add net clzc:zoneclustername:node:net> set address=public_netaddr clzc:zoneclustername:node:net> set physical=adapter clzc:zoneclustername:node:net> end clzc:zoneclustername:node> end clzc:zoneclustername> exit

5. Verify the zone cluster configuration.

   The verify subcommand checks for the availability of the specified resources. If the clzonecluster verify command succeeds, there is no output.

   phys-schost-1# clzonecluster verify zoneclustername phys-schost-1# clzonecluster status zoneclustername === Zone Clusters === --- Zone Cluster Status --- Name Node Name Zone HostName Status Zone Status ---- --------- ------------- ------ ----------- zone basenode1 zone-1 Offline Running basenode2 zone-2 Offline Running

6. Install and boot the cluster.

   phys-schost-1# clzonecluster install zoneclustername Waiting for zone install commands to complete on all the nodes of the zone cluster "zoneclustername"... Installation of the zone cluster might take several minutes phys-schost-1# clzonecluster boot zoneclustername Waiting for zone boot commands to complete on all the nodes of the zone cluster "zoneclustername"...

Example 6–2 Configuration File to Create a Zone Cluster

The following example shows the contents of a command file that can be used with the clzonecluster utility to create a zone cluster. The file contains the series of clzonecluster commands that you would input manually.

In the following configuration, the zone cluster sczone is created on the global-cluster node phys-schost-1. The zone cluster uses /zones/sczone as the zone path. The first node of the zone cluster is assigned the hostname zc-host-1 and uses the public-network address 172.16.0.1 and the bge0 adapter. The second node of the zone cluster is created on the global-cluster node phys-schost-2. This second zone-cluster node is assigned the hostname zc-host-2 and uses the public-network address 172.16.0.2 and the bge1 adapter.

create
set zonepath=/zones/sczone
add node
set physical-host=phys-schost-1
set hostname=zc-host-1
add net
set address=172.16.0.1
set physical=bge0
end
end
add sysid
set root_password=encrypted_password
end
add node
set physical-host=phys-schost-2
set hostname=zc-host-2
add net
set address=172.16.0.2
set physical=bge1
end
end
commit
exit

Example 6–3 Creating a Zone Cluster by Using a Configuration File.

The following example shows the commands to create the new zone cluster sczone on the global-cluster node phys-schost-1 by using the configuration file sczone-config. The hostnames of the zone-cluster nodes are zc-host-1 and zc-host-2.

phys-schost-1# clzonecluster configure -f sczone-config sczone
phys-schost-1# clzonecluster verify sczone
phys-schost-1# clzonecluster install sczone
Waiting for zone install commands to complete on all the nodes of the 
zone cluster "sczone"...
phys-schost-1# clzonecluster boot sczone
Waiting for zone boot commands to complete on all the nodes of the 
zone cluster "sczone"...
phys-schost-1# clzonecluster status sczone
